SPECIFICATION forming part of Letters Patent No. 376,648, dated January 17, 1888.

.Applieation filed June 9, 1887. Serial No. 240,755.

To all. whmn it may concern.-

Be it known that we, WILLIAM J. GRoNER and CHARLES G. CONN, citizens of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Music-Folios, of which the following is a full, clear, and exact description.

Our invention relates to a music-folio having a brace or supporter on one leaf capable of being arranged to support the other leaf and to hold the music spread out before the performer, and further, of means for holding the leaves in place and prevent their being blown about by the wind, and to fasten the folio together when not in use.

To these ends our invention consists in the construction which will first be described with reference to the accompanying drawings, in whioh Figure I represents the folio in extended position, both of the braces or supporters be ing arranged to support the upper leaf of the folio. Fig. II is a similar view showing one supporter turned down to hold the lower leaves of music from flying about. Fig. III is a view of the folio folded up. and fastened when not innse. Fig. IV is a perspective view of one of the braces detached.

1 2 may represent, respectively, the lower and upper leaves of a music-folio, in which may be fastened in any manner any number of sheets of music 3. In cases where the music is printed on two pages, it is desirable to have the whole of'both pages spread out before the musician at once, so that he need not stop while playing to turn the music or remove the sheet from the folio when not in use. For this purpose the invention is arranged in the manner shown in Figs. I and II.

4 is an arm pivoted at 5 to the lower leafof the folio and jointed at 6.

(Model.)

7 are spring-arms fixed to the loose end of the joint-arm 4, and so arranged that when said arm is extended under the upper leaf of the folio, as shown in Fig. I, the spring-arms Will bear upon thesheets of music and prevent their flying around. Should it be necessary to hold the lower sheets at the same time, one arm may be turned down in the position shown in Fig. II, the outer end of the arm 4 being turned aboutits joint so as to bring the spring arm in the necessary position. The dotted lines in Fig. II represent one position of the arm while undergoing the change.

When the musiois not being used, the folio may be closed, as shown inFig. III; and then, if the outer ends of the arms be turned about their joints to bring the spring-arms in the proper position, the leaves of the folio may be heldtightly together and loss of the sheets of music contained therein thus prevented.

Having thus described our invention, the following is what we claim as new therein and desire to secure by Letters Patent:

1. In combination with a music-folio, an arm pivoted thereto so as to move in a plane parallel therewith, and a springarm carried by said pivoted arm and adapted to embrace the edge of the folio, substantially as described.

2. The combination of a music-folio whose leaves are hinged together, a jointed arm hav ing one member pivoted to one of said leaves and adapted to move in a plane parallel therewith, and a spring'arm fixed to the other member of said pivoted arm and adapted to embrace the edge of the folio when the latter is in either extended or folded condition, substantially as described.
